Garage Door Lock Service

What Garage Door Locks Does Triton Locksmith Service?

T-handle locks on overhead doors, slide bolt locks, side-mounted deadbolts, and the interior entry door lock. The lock on the overhead garage door itself is the one most people overlook. If your garage has a side entry door or a door leading into the house, those need quality locks too. One weak point compromises the whole system.

Here's what we install and repair on garage doors:

• T-handle lock (overhead door): The keyed lock in the center of the garage door that prevents it from being lifted. When engaged, the door can't be opened manually even if the opener is defeated. $75-$125 installed.
• Slide bolt lock (overhead door): A manual bolt that slides into the track, physically blocking the door from rolling up. Simple but effective. $65-$100 installed.
• Side entry door deadbolt: Many garages have a walk-through door on the side. This needs a proper Grade 1 deadbolt just like your front door. $120-$200 installed.
• Interior entry door (garage to house): The door from the garage into your home. This is the last line of defense if someone gets into the garage. Needs a solid deadbolt with 3-inch strike plate screws. $120-$200 installed.

We see a lot of garages in South Florida with zero locks. People rely entirely on the automatic opener and assume that's enough. It's not. And here's why.

Why Is Your Garage Door the Biggest Security Risk?

Because the emergency release cord on most automatic openers can be tripped from outside in 6 seconds. Here's how. The top panel of your garage door has a small gap between the door and the frame. A coat hanger or stiff wire can be inserted through that gap, hooked around the emergency release cord, and pulled. The opener disconnects. The door lifts manually by hand. No noise, no forced entry, no evidence. The burglar walks into your garage.

This isn't theoretical. It's a documented technique. According to the International Association of Certified Home Inspectors (InterNACHI), 9% of burglars enter through the garage. YouTube has dozens of videos showing the coat hanger method. It works on virtually every standard automatic garage door opener.

A T-handle lock or slide bolt stops this cold. When the manual lock is engaged, the door physically can't be lifted even with the opener disconnected. It's a $75-$125 investment that closes the single biggest vulnerability in most homes.

How Much Does Garage Door Lock Service Cost?

$75-$200 depending on the lock type and door.

• T-handle lock replacement: $75-$125 (hardware is $30-$50, labor is the rest)
• Slide bolt installation: $65-$100
• Side entry door deadbolt: $120-$175
• Interior door (garage to house) deadbolt: $120-$200
• T-handle lock repair: $65-$95
• Garage door lock rekey: $85-$125

If you're getting the overhead door lock and the interior entry door lock done at the same time, we handle both in one visit. Total for both is typically $175-$275 depending on the hardware grade.

What About the Door from the Garage into the House?

This is the door most homeowners forget to secure. If someone gets into your garage (through the emergency release, an unlocked side door, or a left-open main door), the door between the garage and the house is the only thing between them and your living space. In many homes, this door has a cheap knob lock with no deadbolt. Some don't even have a lock at all.

We recommend a minimum of an ANSI Grade 1 deadbolt on this door with 3-inch strike plate screws. This is the same recommendation we make for front doors. If someone is inside your garage, this door is your front door. Treat it like one.

For families with the garage as a daily entry point (most South Florida homes use the garage more than the front door), a keypad deadbolt on this door is convenient. Punch in a code when your hands are full of groceries. No key fumbling. $150-$300 installed.

Should You Unplug the Garage Door Opener When on Vacation?

Yes, if you've also engaged the manual lock. When you lock the T-handle or slide bolt and unplug the opener, you've eliminated both the remote and the emergency release as entry methods. The door can't be opened without physically breaking it. For vacations or extended absences, this is the setup we recommend. See our vacation security checklist for the full protocol.

Some older garage door openers use fixed-frequency remotes that can be cloned with a universal remote from Amazon. Unplugging the opener during vacations eliminates this risk entirely. Newer openers with rolling code technology (Chamberlain, LiftMaster) are much harder to clone, but unplugging is still good practice for extended absences.

Can You Fix a Broken T-Handle Lock?

Usually we replace rather than repair. T-handle mechanisms are inexpensive ($30-$50 for the part) and replacement is faster and more reliable than trying to fix a worn one. The internal springs and cams fatigue over time. If the key turns but the bars don't extend into the track, the cam is likely broken. New T-handle, new keys, 30 minutes, done.

If the lock cylinder itself is just sticky from corrosion (common in South Florida), we can sometimes clean and lubricate it. But if you're paying us a service call anyway, swapping in a new T-handle for an extra $30 is usually the smarter move. Fresh hardware, fresh springs, fresh keys. No callbacks.
